.....fumbling a slide is an occupational hazard these days..
lose a specimen..always have others in the queue..
[..i really do need to get some more slides though..so few
remain..Muppet Labs is a Danger Zone for all things glass..]
.............
...I suspect I may be staring at the phenomena that results in
morg lesions almost never getting infected.
I did find that quite surprising over the last 2.5 years..no matter
how large and generally nasty looking a morg lesion is..it does
not really get infected by bacteria. I'll see some inflammation
around the edges..but not purulent..not seeping pus.
something is killing/inhibiting/lysing the bacteria in the lesion.
but what?
I think I found the smoking gun. It's the morg gels that are
killing off the bacteria around them.

...the bacteria are very thick in this specimen [tiny green dots]
the area around the transparent gel structure is clear of bacteria.
They are simply...gone.
The morg gels are
made by the very bacteria that they kill off once they start
making the gels. Whatever "brother" bacteria that is not involved
in the colony under the morg gel..is doomed. It just vanishes.
The bacteria not just "dead"..a dead bacteria would still leave a tiny
particle corpse. The bacteria is missing. It has been dissolved.
I suspect that the bacteria that goes missing has been broken
apart [lysed] and used as fuel to grow the rapidly growing gel
structures.
The bacteria produced gels are thick in the morg lesions. If the
gel can lyse all bacteria,
and not just "their own kind", it would neatly explain why the
lesions do not become infected with pathogenic bacteria.
